Abstract
(EN) Disclosed are a mobile terminal with a reduced handoff delay time and a wireless network system comprising same. A mobile terminal according to one embodiment of the present invention comprises: a sensor unit for generating azimuth angle data; a memory unit which stores a base station table containing data about a next base station corresponding to the orientation of the mobile terminal in the current base station; and a handoff management unit which searches for one or more next base station(s) by using the azimuth angle data from the sensor unit and the base station table, and performs a scanning action with respect to the found next base station(s) in accordance with the search results.
(FR) L'invention porte sur un terminal mobile à retard de transfert intercellulaire réduit et sur un système de réseau sans fil le comprenant. Un terminal mobile selon un mode de réalisation de la présente invention comprend : une unité de capteur pour générer des données d'angle d'azimut; une unité de mémoire qui stocke une table de stations de base contenant des données concernant une station de base suivante correspondant à l'orientation du terminal mobile dans la station de base courante; et une unité de gestion de transfert intercellulaire qui recherche une ou plusieurs stations de base suivantes par utilisation des données d'angle d'azimut provenant de l'unité de capteur et de la table de stations de base, et effectue une action de balayage relativement à la ou aux stations de base suivantes trouvées conformément aux résultats de recherche.
(KO) 핸드오프 지연 시간을 감소시킨 이동 단말기 및 이를 포함하는 무선 네트워크 시스템이 개시된다. 본 발명의 일실시예에 따른 이동 단말기는, 방위각 정보를 발생하는 센서부와, 현재 기지국 내의 상기 이동 단말기의 방향에 대응하는 다음 기지국의 정보를 포함하는 기지국 테이블이 저장된 메모리부 및 상기 센서부로부터의 방위각 정보 및 상기 기지국 테이블을 이용하여 하나 이상의 다음 기지국을 검색하고, 상기 검색 결과에 따라 검색된 다음 기지국들에 대한 스캐닝 동작을 수행하는 핸드오프 관리부를 구비하는 것을 특징으로 한다.
